Assessment of CFD methods in predicting flow regime and pressure gradient in two phase gas-liquid vertical flow
(Master thesis, 2020)Available tools for dealing with multi-phase flows are not effective with complex geometries such as process piping with combination of horizontal and vertical pipes, bends and valves. However, rapid development of ... -
Comparison of OpenFoam and ANSYS Fluent. Compitational Fluid Dynamic Simulation of Gas-Gas Single Phase Mixing with and without Static Mixer
(Chapter; Peer reviewed, 2016)Gas-gas single phase mixing were numerically evaluated with static mixer and without static mixer using OpenFoam and ANSYS Fluent codes. The main goal was the gas-gas mixing simulation comparison between ANSYS Fluent and ... -
Computational study of fingering phenomenon in heavy oil reservoir with water drive
(Journal article, 2015)The objective of this paper is to numerically study the flow in heavy oil reservoir with water drive. The main focus is to investigate the viscous fingering phenomenon and how it affects the oil recovery. Two-dimensional ... -
Computational Study of Heavy Oil Production with Inflow Control Devices
(Journal article; Peer reviewed, 2015-11-25)Recovery of heavy oil is associated with challenges in terms of early water or gas breakthrough caused by the fingering phenomenon. This study is related to Californian heavy oil production and includes 2D simulations of ... -
Heavy Oil Production With Energy Effective Steam-assisted Gravity Drainage
(Journal article; Peer reviewed, 2016)In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the viscosity, in order to extract the oil. Steam-assisted gravity drainage (SAGD) is a thermal method where continuous steam injection is ... -
Recommendation of a model for simulating & analysis of the influence of particle size distribution on the simulations of bubbling fluidized beds
(Master thesis, 2008-06-06)A computational study of the influence of particle size distribution on bubbling fluidized beds is performed. Several simulations are performed using Eulerian multiphase model for a two dimensional fluidized bed with an ... -
Simulating open channel flow for drill mud mass flow measurement, part II
(Master thesis, 2015-11-06)Advancement in oil drilling technology, particularly managed pressure drilling requires better knowledge of return drill mud flow. Since the mud outflow is in an open channel, it is proposed to use flume with constriction ... -
Simulation of flow in sedimentation tank using FLUENT
(Master thesis, 2015-10-09)Sewage treatment is the process which removes majority of the contaminants from a sewage stream and produces a liquid effluent suitable for safe disposal into the natural environment and sludge. Physical, chemical and ... -
Simulation of Hydrogen Tank Refuelling
(Master thesis, 2020)As an alternative to fossil fuels and as a sustainable energy carrier, there are considerable interestsin investigating hydrogen. Hence, it seems significant to evaluate the behavior of hydrogen in refueling or storing. ... -

Transient drilling fluid flow in Venturi channels: comparing 3D and 1D models to experimental data
(Doctoral dissertations at the University of South-Eastern Norway;41, Doctoral thesis, 2019-09-26)In well drilling operations, bottom hole pressure control within a narrow pressure margin has a high risk of influx (kick) and outflux (loss) at greater depths. Kick occurs when the formation pressure is higher than ... -
Wind energy; CFD simulation of wakes and wind turbine forces
(Master thesis, 2015-09-18)Wind power is a clean and renewable energy source, which plays an important role in the world's energy landscape. When developing a wind farm it is beneficial to analyze the flow pattern in order to maximize the total ...
